專業(yè)的設(shè)備處理高電壓能量收集

　　能量收集往往涉及權(quán)力清除涓涓細(xì)流從非常低的能量環(huán)境來(lái)源。對(duì)于這些應(yīng)用程序，設(shè)計(jì)人員專注于電路能夠轉(zhuǎn)換到最小的可用電壓電平的有用功率。與此相反，高能量的來(lái)源需要一類電路能夠有效地處理高電壓水平的能量傳感器，如太陽(yáng)能電池板，熱電發(fā)電機(jī)，壓電設(shè)備。設(shè)計(jì)師可以使用從制造商包括線性技術(shù)中，半導(dǎo)體、羅姆半導(dǎo)體、意法半導(dǎo)體器件實(shí)現(xiàn)高效的高壓能量收集系統(tǒng)，德克薩斯文書(shū)，其中。

　　低能量的應(yīng)用，高效的能量收集芯片等先進(jìn)設(shè)備eh4205線性模塊，線性技術(shù)LTC3108、德克薩斯文書(shū)bq25570旨在清除功率從換能器產(chǎn)生有限的電壓水平低20 mV，最大值為6 V左右。在這些系統(tǒng)的核心，升壓轉(zhuǎn)換器帶來(lái)低電壓到有用的水平供電電路和充電超級(jí)電容器和電池。

　　High-energy sources and their respective transducers can produce output-voltage levels easily exceeding the maximum input range of these low-voltage devices. For example， solar panels such as the Phoenix Contact 2885456 module produce nearly 18 V output. Driven by high-amplitude vibrations in industrial applications and other high-energy environments， piezoelectric devices can achieve output levels in the tens of volts. Similarly， thermoelectric generators can produce similar voltage output levels when a sufficiently large temperature differential exists between the two sides of a TEG， although achieving that temperature differential can be a difficult task at best.
